If the probability of happening of an event is p, then the probability of it not happening is:

1. p

2. p − 1

3. 1 − p

4. $1 - \Big(\dfrac{1}{p}\Big)$

The probability of getting a number divisible by 3 in throwing a die is:

1. $\Big(\dfrac{1}{6}\Big)$

2. $\Big(\dfrac{1}{3}\Big)$

3. $\Big(\dfrac{1}{2}\Big)$

4. $\Big(\dfrac{2}{3}\Big)$

In a single throw of a die, the probability of getting a number greater than 4 is:

1. $\Big(\dfrac{1}{2}\Big)$

2. $\Big(\dfrac{1}{3}\Big)$

3. $\Big(\dfrac{1}{4}\Big)$

4. $\Big(\dfrac{2}{3}\Big)$

In a single throw of a die, the probability of getting a prime number, is:

1. $\Big(\dfrac{1}{2}\Big)$

2. $\Big(\dfrac{1}{3}\Big)$

3. $\Big(\dfrac{1}{4}\Big)$

4. $\Big(\dfrac{2}{3}\Big)$
